This is interesting, researchers have found a new longer form of PTEN a tumour suppressor gene.  They found that unlike the normal form of PTEN that is isolated within a cell this version can move to neighbouring cells.  They also showed that the longer version of PTEN helped reduced the size of tumours both in mice and in the petri dish.
